Abstract
The approach to the primary structure of gray cast iron as an analog of a composite material reinforced with discrete fibers is used to study the quantitative contributions of dendrites and a eutectic matrix to the ultimate tensile strength. A coefficient of adhesion of a dendrite to a eutectic matrix, which is almost independent of the strength of gray cast iron, is proposed to calculate the stress of separation of dendrites from a eutectic matrix. A phenomenological model is developed to estimate the strength of gray cast iron.
